Real men don't cry because they are not supposed to be emotional. I almost cried (ie got pretty choked up) when I thought I was dying. My dad starts to cry a bit when he starts talking about his cancer prognosis. Other than that he has never cried that I know of, although my mom said he cried when I was born but I have no way to verify obviously.
Many men rarely let other men, including their own children, witness them shed any tears.
I think I can guarantee that, privately, or only witnessed by the lady of the family, all mean have shed tears.
Unless a particular man has never experienced true loss or extreme trauma, I won't believe otherwise.
Most men try to refrain from ever shedding tears over trivial shit though. The boss got heated up and said something in a bad way? A person of no relation died? A movie was extremely sappy, sad, somber, etc?
Women cry/shed tears because they are moved emotionally far faster/more effectively than men are, and there's also no judgment ever rendered for getting emotional as a female, it's expected.
There's three judgments possible for when a man, out of nowhere, is suddenly crying. He either just broke down after holding some pain/sorrow real close to the chest, he's mental, or he's feminine and possibly homosexual (could just be a feminine straight man - remember, I'm describing what others will think). That's basically what the world has dictated and it's been that way. Men can be just as emotionally moved by movies that a female is crying. I can't answer how many men feel like, if there was never a negative opinion of men crying, they'd actually shed tear over a movie or something.
I don't buy that men are truly emotionally cold, or meant to be - they're expected to be that way, particularly because historically, men have had to put up with some terrible scenes and painful decisions.. and the expectation is that those decisions and choices and what has been witnessed, won't be of any negative repercussions to the emotional and mental stability of that man.
I'm curious, however, if that trend, which tends to produce men "holding things in" because they don't dare share and spill their emotions and thoughts, has directly produced such extreme numbers of PTSD and similar repercussions for those men. We humans, including men, should be able to deal with what we see - but men especially have had to deal with the stigma that even "seeing a shrink" is "not manly."
The solution isn't necessarily men crying more, I just thought this was an interesting point to bring to the discussion.
